I am using tkiner mesagebox and ttk progressbar with Python 3. I try to set a text window in one line and a progressbar in the next line. This is working so far, but I am not able to change the colour from green (default) to another value. With this post How to change ttk.progressBar color in python I was able to turn the colour to black, but then I don't know how to get the text over it. Can someone help me?
from tkinter import *
from tkinter import messagebox
from tkinter import ttk
#bar in green with text
root = Tk()
gpw_l1 = Label(root, text="This should be a black bar")
gpw_l2 = ttk.Progressbar(root, orient="horizontal", length=500, mode="determinate")
gpw_l2.grid(row=2, column=0, pady=10)
gpw_l2["maximum"] = 1.0
x = 0.7
gpw_l2["value"] = x
gpw_l1.grid(row=0, columnspan=2)
gpw_l2.grid(row=1, columnspan=2)
root.geometry('+100+200')
root.mainloop()
root.quit()
#bar in red, but no text
root2 = Tk()
frame = Frame(root2)
frame.grid()
s = ttk.Style()
s.theme_use('clam')
s.configure("red.Horizontal.TProgressbar", foreground='red', background='black')
ttk.Progressbar(frame, style="red.Horizontal.TProgressbar", orient="horizontal", length=600, mode="determinate",
maximum=4, value=1).grid(row=1, column=1)
frame.pack()
root2.mainloop()
root2.quit()
from tkinter import *
from tkinter import messagebox
from tkinter import ttk
#bar in red, but no text
root2 = Tk()
frame = Frame(root2)
frame.grid()
s = ttk.Style()
s.theme_use('clam')
s.configure("red.Horizontal.TProgressbar", foreground='red', background='black')
gpw_l1 = Label(frame, text="This should be a black bar").grid(row=1, column=1)
ttk.Progressbar(frame, style="red.Horizontal.TProgressbar", orient="horizontal", length=600, mode="determinate",
maximum=4, value=1).grid(row=2, column=1)
frame.pack()
root2.mainloop()

I am making a text base game and would like to get a new root window on the click of a button while simultaneously closing the original one?

i've the problem for make an GUI apps with python tkinter.
here is my sample code
import tkinter as tk
from tkinter import ttk
root = tk.Tk()
root.geometry('300x300')
root.title('CSV Editor')
notebook = ttk.Notebook(root)
notebook.pack(pady=10, expand=True)
tab_home = ttk.Frame(notebook, width=300, height=300)
notebook.add(tab_home, text='Home')
fr_home = tk.Frame(tab_home, background="white")
fr_home.grid(row=0, column=0)
fr_home_container_canvas = tk.Frame(fr_home, background="red")
fr_home_container_canvas.grid(row=0, column=0, sticky='nw')
fr_home_container_canvas.grid_rowconfigure(0, weight=1)
fr_home_container_canvas.grid_columnconfigure(0, weight=1)
fr_home_container_canvas.grid_propagate(False)
canvas_home = tk.Canvas(fr_home_container_canvas)
canvas_home.grid(row=0, column=0, sticky="news")
vsb = tk.Scrollbar(fr_home_container_canvas, orient="vertical", command=canvas_home.yview)
vsb.grid(row=0, column=1, sticky='ns')
canvas_home.configure(yscrollcommand=vsb.set)
fr_home_widget_canvas = tk.Frame(canvas_home, background="yellow")
canvas_home.create_window((0, 0), window=fr_home_widget_canvas, anchor='nw')
fr_home_widget_canvas.config(width=300, height=300, padx=10)
fr_home_container_canvas.config(width=300, height=300)
canvas_home.config(scrollregion=canvas_home.bbox("all"))
text_widget = tk.Text(fr_home_widget_canvas, width = 30, height = 10)
text_widget.grid(column=0, row=0)
root.mainloop()
if i run this code, this is the preview
enter image description here
but when i click inside the text widget, in the frame appear line / border like this
enter image description here
What is that line / border? how to remove it?
thank you so much :)
It is the highlight background which can be removed by setting highlightthickness=0:
canvas_home = tk.Canvas(fr_home_container_canvas, highlightthickness=0)
I created a main root with two frames.
One frame is for program toolbar.
The other frame is for a canvas where data will be displayed and for a scrollbar widget.
Inside of the canvas is a third smaller frame which will be used for scrolling trough data.
However, when I try to define new widgets inside of a function call, the scroll button loses its functionality. That smaller frame is scrollable only if I define these widgets in the top level of the code.
I used a simple for loop to create labels just for testing.
Could anyone tell what I am doing wrong?
from tkinter import *
from tkinter import ttk
#Creating main window
root = Tk()
root.resizable(width=False, height=False)
#Defining Background
toolbar = Frame(root, width=613, height=114)
toolbar.grid(row=0, column=0)
background_frame = Frame(root, width=615, height=560)
background_frame.grid(row=1, column=0)
background = Canvas(background_frame, width=615, height=560)
background.pack(side=LEFT, fill=BOTH, expand=1)
scroll_bar = ttk.Scrollbar(background_frame, orient=VERTICAL, command=background.yview)
scroll_bar.pack(side=RIGHT, fill=Y)
background.configure(yscrollcommand=scroll_bar.set)
background.bind('<Configure>', lambda e:background.configure(scrollregion = background.bbox('all')))
second_frame = Frame(background)
background.create_window(150,100, window=second_frame, anchor='nw')
def confirm1():
for x in range(100):
Label(second_frame, text = x ).grid(row=x, column=1)
show_labels = Button(toolbar, text= "Show labels", fg="black", command=confirm1)
show_labels.grid(row=0, column=2)
root.mainloop()
You need to to update the background canvas' scrollregion whenever you add widgets to the second_frame. That's easy to do by binding to that frame's <Configure> event.
Here's a complete version of your code with a couple of lines added (# WHERE INDICATED) to do that:
from tkinter import *
from tkinter import ttk
#Creating main window
root = Tk()
root.resizable(width=False, height=False)
#Defining Background
toolbar = Frame(root, width=613, height=114)
toolbar.grid(row=0, column=0)
background_frame = Frame(root, width=615, height=560)
background_frame.grid(row=1, column=0)
background = Canvas(background_frame, width=615, height=560)
background.pack(side=LEFT, fill=BOTH, expand=1)
scroll_bar = ttk.Scrollbar(background_frame, orient=VERTICAL, command=background.yview)
scroll_bar.pack(side=RIGHT, fill=Y)
background.configure(yscrollcommand=scroll_bar.set)
# NOT NEEDED
#background.bind('<Configure>',
# lambda e: background.configure(scrollregion=background.bbox('all')))
second_frame = Frame(background)
background.create_window(150,100, window=second_frame, anchor='nw')
# ADDED
second_frame.bind('<Configure>',
lambda e: background.configure(scrollregion=background.bbox('all')))
def confirm1():
for x in range(100):
Label(second_frame, text=x).grid(row=x, column=1)
show_labels = Button(toolbar, text="Show labels", fg="black", command=confirm1)
show_labels.grid(row=0, column=2)
root.mainloop()
Result after clicking button and scrolling the canvas region:
So I want this Tkinter entry but I can't find it what am I doing wrong?
import tkinter as tk
import math
import time
root = tk.Tk()
root.geometry()
root.attributes("-fullscreen", True)
exit_button = tk.Button(root, text = "Exit", command = root.destroy)
exit_button.place(x=1506, y=0)
frame = tk.Frame(root)
main_entry = tk.Entry(root, width = 100, fg = "black").place()
frame.place(relx=.5,rely=.5, anchor='center')
root.mainloop()
I want to make the entry show, why is gone I did everything right?
here, put layout options on variables like this (if You want to just place a widget somewhere use .pack which also does not necessarily require arguments):
import tkinter as tk
import math
import time
root = tk.Tk()
root.geometry()
root.attributes("-fullscreen", True)
exit_button = tk.Button(root, text = "Exit", command = root.destroy)
exit_button.place(x=1506, y=0)
frame = tk.Frame(root)
main_entry = tk.Entry(root, width = 100, fg = "black")
main_entry.place(x=50, y=50)
frame.place(relx=.5,rely=.5, anchor='center')
root.mainloop()
I am trying to learn Tkinter and python. How can I open multiple images and save it on multiple canvas in Python 3? I also want the image to fit just perfect on to the size of the canvas.
Could someone show me to do this using simple code.
import tkinter
from tkinter import filedialog
import os
#from PIL import ImageTk, Image
from tkinter import *
import PIL.Image
from tkinter.filedialog import askopenfilename
import py_compile
mainWindow =tkinter.Tk()
mainWindow.title("Image")
mainWindow.geometry('640x480+800+200')
mainWindow.columnconfigure(0, weight=3)
mainWindow.columnconfigure(1, weight=1)
mainWindow.columnconfigure(2, weight=1)
mainWindow.rowconfigure(0, weight=3)
mainWindow.rowconfigure(1, weight=3)
mainWindow.rowconfigure(2, weight=5)
mainWindow.rowconfigure(3, weight=3)
leftFrame = tkinter.LabelFrame(mainWindow, text='PICTURE')
leftFrame.grid()
canvas = tkinter.Canvas(leftFrame, relief='sunken', borderwidth=5, bg= 'white', width=100, height=100)
canvas.grid(row=1, column=0)
canvas2 = tkinter.Canvas(leftFrame, relief='sunken', borderwidth=5, bg= 'white', width=100, height=100)
canvas2.grid(row=2, column=0)
canvas3 = tkinter.Canvas(leftFrame, relief='sunken', borderwidth=5, bg= 'white', width=100, height=100)
canvas3.grid(row=1, column=1)
canvas4 = tkinter.Canvas(leftFrame, relief='sunken', borderwidth=5, bg= 'white', width=100, height=100)
canvas4.grid(row=2, column=1)
def clicked():
print('hello')
open_img()
def open_img():
global photo
filename = filedialog.askopenfilename(initialdir = "E:/Images", filetypes = ())
photo = tkinter.PhotoImage(file=filename)
photo = photo.subsample(3,3)
canvas.create_image(0,0, anchor=CENTER, image=photo)
rightFrame = tkinter.LabelFrame(mainWindow, text='MENU')
rightFrame.grid()
button1 = tkinter.Button(rightFrame , text="Open", command=clicked)
button1.grid(row=1, column=2)
mainWindow.mainloop()
You would use one class with each image creating an instance of that class, but since you have not used a class and so are probably not familiar with the class structure, the following code combines everything into one class. Since I don't have the images, this opens a new Toplevel with a related "close" button instead of an image, each time the "open" button is clicked.
try:
import Tkinter as tk ## Python 2.x
except ImportError:
import tkinter as tk ## Python 3.x
from functools import partial
class OpenToplevels():
""" open and close additional Toplevels with a button
"""
def __init__(self):
self.root = tk.Tk()
self.button_ctr=0
but=tk.Button(self.root, text="Open a Toplevel",
command=self.open_another)
but.grid(row=0, column=0)
tk.Button(self.root, text="Exit Tkinter", bg="red",
command=self.root.quit).grid(row=1, column=0, sticky="we")
self.root.mainloop()
def close_it(self, id):
id.destroy()
def open_another(self):
self.button_ctr += 1
id = tk.Toplevel(self.root)
id.title("Toplevel #%d" % (self.button_ctr))
tk.Button(id, text="Close Toplevel #%d" % (self.button_ctr),
command=partial(self.close_it, id),
bg="orange", width=20).grid(row=1, column=0)
Ot=OpenToplevels()
